Cell Phone Jammers Can Affect Base Station Communications

Cell phone jammers, although called jammers, don’t actually block data signals, but look like a data cell phone jammer. Generally speaking, the communication between a mobile phone and a smart phone is based on a communication base station, that is, a mobile phone-communication base station-mobile phone. The mobile phone signal jammer will affect the communication between the mobile phone and the communication base station, resulting in the failure of normal transmission. However, because the communication base station is public on mobile phones within a certain range, it often occurs that there is no data signal in the examination room and cannot be used normally.

The current mobile phone signal jammers on the market can only limit the data signal with a half length > 20 meters beyond 500M meters from the transmission tower. The shielding radius is adjustable. It only shields the data signal and will not cause harm to other electronic products. So if you are not in the exam room recently and the data signal is not very good, don’t worry about blaming the cell phone signal jammer, or it may be your own cell phone problem.

Air conditioners are now commonly installed in schools. When the weather is too hot, the school will turn on the air conditioner or fan to ensure the safety of candidates. At this time, the temperature of the cell phone signal jammer will also drop. In fact, this thing is like a mobile phone. In summer, just open it and it will be hot. But will not damage the machine.
